About Mac parts and service history
If certain parts in your Mac have been repaired, you can check Parts & Service in System Settings to find out if the repair was done using genuine Apple parts. If you sell or give away your Mac, the new owner can also find out about its repair history.

Unknown: In some situations, such as if the part was replaced with a non-genuine part or the part isn't working as expected, you see this label.
Used: The part was already used or installed in another Mac.

Find out about genuine Apple parts
Genuine Apple parts are individually calibrated with data uploaded to Apple's servers and stored at the time of manufacture; this data is then retrieved to finish the repair. This calibration process ensures that parts meet performance, security, privacy and safety expectations.
If you don't finish the repair, you can continue using your device, but the part may not perform as well as a calibrated part. For example, you won't be able to use Touch ID to unlock your device or to sign in to apps until the calibration process is completed for those parts. In Parts & Service, your device will show Finish Repair next to the part until you finish the repair with Repair Assistant.
If the service was completed using genuine Apple parts and calibration processes, you'll see Genuine or Used next to the part.1 After the service is completed and your Mac connects to the internet, you can click on the part for more information, including the date of the service.
Find out about the message Unknown
The message Unknown can appear for several reasons, including when the replacement part:
Is non-genuine
Isn't functioning as expected
Hasn't been verified and linked to your Mac after the repair was completed
Has been modified or is otherwise unable to be verified
If an unknown part is detected, your Mac will show a notification the first time you unlock it after a repair and another one 5 days later.
If an issue with a component significantly affects the functionality of the device and needs attention to resolve, your Mac shows a one-off notification. This notification appears the first time you unlock your Mac after the issue is detected, and the notification remains in Parts and Service History until you dismiss it.
Find out about repair options
When you need to repair your Mac, you can choose between several options. For most customers, visiting a professional repair provider with certified technicians who use genuine Apple parts is the best way to get a safe and reliable outcome to a repair. These providers include Apple and Apple Authorised Service Providers. Independent Repair Providers also have access to genuine Apple parts.2 Genuine Apple parts are designed to fit precisely within the device and provide optimal performance, safety and reliability. Repairs performed by Apple and Apple Authorised Service Providers are covered by Apple's warranty.
Depending on your location, you can get your Mac serviced – in or out of warranty – by visiting an Apple Store or Apple Authorised Service Provider, or by sending your Mac to an Apple Repair Centre. Genuine Apple parts are also available for out-of-warranty repairs from Independent Repair Providers or through Self Service Repair.3
Repairs performed by untrained individuals or using non-genuine parts may affect the functionality, safety, security and privacy of the device.

A previously used part may function in a different Mac, but because of prior use or modification, the performance and quality might be inconsistent.
Independent Repair Providers have access to genuine Apple parts, tools, training, service guides, diagnostics and resources. Repairs by Independent Repair Providers are not covered by Apple's warranty or AppleCare plans but may be covered by the provider's own repair warranty.
Self Service Repair provides access to genuine Apple parts, tools and repair manuals so that customers who are experienced with the complexities of repairing electronic devices can perform their own out-of-warranty repairs. Self Service Repair is currently available in certain countries or regions for specific Mac models introduced in 2020 or later.
